ATTACHMENT FOR LOOMS.

A pplieation filed April 17, 1923. Serial No. 632,643.

To all 10 lap m, it mag concern Be it known that LARrrron J. Amer, acitizen of the United States, and a. resident of Middletown, in thecounty of Middlesex and the State of Connecticut, have invented acertain new and useful Improvement in Attachments for Looms, of which.the. following is a specification.

My invention relates more especially to a device for enabling the fabricbeing produced in a loom to be accurately positioned, after it has beenmoved for any purpose, so that the weaving will be resumed at the properpoint and without leaving any im: perfection in the cloth.

ne form of device embodying my ipyention and in the construction use ofwhich the objects herein set out, aswell as others, may be attained, isillustrated in; the accompanying drawings, in which-.-

Fig. 1 is a view of a portion of, a loom showing my improved deviceapplied to the breast-beam thereof, the dotted lines show ing theposition of the adjusting device as overlying. the fabric when not inuse.

Fig. 2 is a view in section through a reed and breast-beam of a loom ona plane denoted by the dotted line 2-2 of Fig. 1, and showing myimproved device in place thereon.

In the operation of weaving, when a dc fective place appears in thefabric and as soon as it has been detected, the loom is stopped, and isturned forward by hand so that the fabric is moved to an accessibleposition and the imperfection is removed by picking out the weftthreads, and the loom is then turned back to locate the fabric, asnearly as possible, in the position it occupied before it was movedforward, and the weaving is then resumed. In thus returning the fabricto its former and weaving position,

it is a very difiicult matter, and requires much time, care and skill,to locate the fabrio in such position that the Weaving will again betaken up in the proper place and without leaving an imperfection in thefabric. It is to obviate this difficulty that I have produced myimproved device, and by its use the fabric in the loom, after havingbeen moved for any reason, may be quickly returned to its correctweaving position and may be so accurately placed that the weaving willagain take place at the point where it terminated, and therefore noimperfection will occur in the fabric by reason of the interruption inthe weaving process.

Such device is shown in the accompanying drawings in which there. isillustrated one end of the breast beam 4 of a Loom secured to one of itssupports 5 said; beam having guide rolls. 6-7mounted therein to receivethe woven fabric 8. This fabricterminatesin theusu'al manner: at pointef weaving, this-being the point where the woven fabric joins the shed 10, shed extending. in the usual manner through the reed 11. All of theparts thus far described are of old and well known construction and willbe readily understood by those. skilled in the art without furtherreferenceherein.

P q l y ma te 0. t ase 1 and s. fam d t ne dir st joa aby means of a spring 15 An indicating fina 16 adiu blr secur d. to. hePeter in any suitable manner, in the construction shown the end of thefinger passing through a pivot stud 17 mounted in the pointer, whichpointer is adjustably held in said stud as by means of adjusting nuts 18engaging the thr-eaded end of the finger. The opposite end of the fingeris bent as at 19 so that it may be engaged within the cross of the shed10, and is shown in Figs. 1 and 2 of the drawings. 7

This device, in aflixing it to the breastbeam, is sopositioned that thebent end 19 of the finger will engage within the crotch of the shed 10and approximately in a line that will be traversed by the weft thread asit is carried through the shed by the bobbin, and the pointer, in thisposition of the finger, will be registered with the zero point, or suchother point as may be desired. Having thus been properly adjusted the'finger may be located in its inoperative position overlying the fabricand as shown in dotted lines in Fig. 1 of the drawing. When the fabricbeing woven is moved from its weaving position for any reason, and ashereinbefo-re referred to, and it is desired to again place it in itsweaving position, the following operation takes place. Supposing thefabric to have been moved forward for the purpose of picking outthreads, which is a common operation, the bent end 19 of the finger isplaced between the warp threads comprising the shed and the machine isnow turned backwardly until the fabric is at a point where the engagingfinger moves the hand so that it registers with the zero mark. hen theengaging finger is placed within the shed and between the warp threadsas above described, the spring 15 will move the finger 16 forwardly sothat the finger 19. will engage the crotch, and in the backward movementof the fabric as above described the finger 16 will be swung on itspivot in opposition to the force of the spring 15. When the parts arethus positioned the finger may be removed from the shed, as by swingingit on its pivot against the tension of the spring 15 until the bent end19 is re moved from the shed and the spring 15 will then swing thefinger to an inoperative position, as shown in dotted lines in Figure 1and the machine being started the weaving will again take place at theexact point where it was discontinued, and there will, therefore, be noimperfection in the fabric by reason of the weaving taking place at thewrong point.

In accordance with the provisions of the patent statutes I havedescribed the principles of operation of my invention, together with thedevice which I now consider to represent the best embodiment thereof;but I desire to have it understood that the device shown is onlyillustrative and that the invention may be carried out by other meansand applied to uses other than those above set out.

I claim:

1. A loom including mechanism for weaving a fabric therein, saidmechanism including means for forming a shed, a tensioned horizontallyswinging element normally displaced from the shed and adapted to engagewithin said shed, and an indicating member operatively connected withsaid element to denote its position.

2. A loom including mechanism for weaving a fabric therein, saidmechanism including means for forming a shed, a tensioned engagingmember normally disengaged from the shed and swingingly movable to itsoperative position in a horizontal plane to be engaged within the crotchof said shed, and a means carrying the indicating member for denotingthe position thereof. 3. A loom including mechanism for weaving a fabrictherein, said mechanism including means for forming a shed, anindicating finger to engage within thercrotch of said shed, andan'indicating pointer supporting said finger, said finger having anangle end adapted to be engaged within the crotch of the shed, saidpointer being pivotally mounted to denote the position of said fingerand spring pressed for normally holding the end of the finger engagedwithin said crotch with the finger swingingly movable in a horizontalplane and in operative position when not in use.
